FUEL VAPORIZER AND BURNER.

Application filed March 10, 1915.

To all ivf/0m 'it may concern Be it known that I, LUs'rnR STrLEs, Jr., a citizen ofthe United States, residing at randenburg, in the county of Meade and State of Kentucky, have' invented certain new and useful mprovements in Fuel Vaporizers and Burners, of which the following is a specification. y

rThis invention relates to that type of gaseous fuel burners, especially adapted for use as the heating element in ordinary cook stoves and ranges and more particularly relates to a kerosene burner Iin which the heating flame is rendered smokeless, together with a particular valve mechanism for conjunctive use with such kerosene burner.

As a principal object, this invention contemplates the provision of a gaseous fuel burner and vapor fuel generator which may be depended upon to automatically prepare the fuel before the combustion thereof in such manner as to obviate the nuisance and waste attendant upon a smoky heating flame.

It is a coordinate object to provide a selfindicating valve whereby the number of burners to be ignited may be regulated in any manner desirable with the character of the cooking being carried on.

An object more specific than the foregoing is to provide in a burner of the character set forth a substantially unburnable wick primarily saturated with the originally liquid fuel which may be ignited to institute a vaporizing heat upon adjacent feeding portions of the burner until a continuance of the fuel flow results in the provision for the burner of a gaseous fuel, the heat from the combustion of which provides not only for the usual cooking purposes but also as a generating heat to permit the continuance of such gaseous flow.

The above and additional objects which will become apparent as this explanatory description proceeds, are accomplished by such means as are illustrated in the accompanying drawings, described in the following specification and then more particularly pointed out in the claims which are appended hereto and form a part of this application.

Vfith reference tothe drawings, wherein there is illustrated the preferred embodiment of this invention as it is reduced to practice, and throughout the several views Specification of Letters Patent.

of which like characters of reference designate similar parts: Figure 1 is a plan view of the burner as positioned within a stove of. a customary make, parts being sho-wn in section, Fig. 2 is an elevational view of the stove fitted with the burner of this invention and showing the operation of the indicating portion of the valve, Figs. 3 and et are sectional views taken upon the transverse plane indicated by the respective lines 3-3 and ld of Fig. 1, looking in the directions respectively indicated byA the arrows of such lines, Fig. 5 is a longitudinal section through the burner pipe showing the feed and the .valve controlled burner orifices for such pipe, and Fig. 6 is a perspective view of the valve removed from its seat.

. Referring new to the drawings, and more particularly to Fig. 1, in which the device is most clearly illustrated as a whole the numeral 10 indicates the front and side portions of a cook stove in which a burner such as is eomprehended by this invention is to be desirably positioned. Such a burner inchicles a plurality of longitudinally parallel pipes, one of which as denoted by the numeral 11 connects as indicated at 12 with an inlet pipe 13 for the fuel and is superimposed above the vertically alined burner pipe 14 with which it is connected by means of the laterally disposed pipes 15 and 16 respectively connected by means of suitable elbow joints in the manner indicated at 17 with the burner pipe 14 and the pipe 11,

while at the same time joined with each other at their opposite extremities by means of the transverse piping 18.

The foregoing sets forth the general assemblage of the particular form of burner and gaseous Vapor generator of this invention which may be more particularly described as follows: Split supporting sleeves 19 are maintained by fastening means 2O upon the extremities of the vaporizing pipe 11 and carry the deflector plate 21 extending below such pipe. The pipe 15 is positioned below this deiiector and to one side thereof while the pipe` 16 is similarly positioned slightly above the said deflector in order that flames from the burner pipe 14: may strike the former in preference to the latter. The burner pipe 14 as particularly illustrated in Fig. e has mounted thereon the coacting U-shaped supporting clamps 23 and is conlio" nected by the already discussed means 17 to the pipe 15 in order to receive the heated vapor therefrom. Rotatably positioned within this pipe is the tapered cylindrical valve 2d which is provided with a plurality of elongated openings 25 desirably arranged as illustrated in Fig. G so that portions of all of said apertures may he alined longitudinally with respect to the valve while each of the central apertures extends laterally from such alinement on one side and the extreme apertures extend laterally therefrom in the opposite direction.' One of these central apertures is also elongated as indicated at 26 beyond its counterpart all for the purpose to be hereinafter more fully set forth. Each of these valve apertures is adapted to register with escape or burner openings 25a formed in the pipe le in which the cylindrical valve is snugly seated as before stated. This pipe 111 has one extremity threaded as indicated at 27 to engage with the connection 17 of the pipe l5 in the manner shown at 28 and rotation of the conical valve 24 is controlled by a stem 29 extending through the opposite end. This stem 29 projects through the wall 10 of the stove and carries outwardly thereof the handle 30 for move ment with which there is also mounted upon the stem the indicating finger 31 of an L- shaped formation as illustrated in Fig. l, permitting the finger to rotate in a vertical plane closely parallel to the stove front l0, as the stem is revolved. The portion of the stove front adjacent this linger 31 carries a semicircular scoring provided with indicator marks 32, the vertically central one of which indicates that the full number of burner apertures are in use while the adjacent marks to either side of said vertically central one mean respectively, when the indicator 3l is pointed thereat, that the two end burners or the two side burners, as may be the case, are in use. It is also possible to adjust the valve 2l through its handle so that the elongated portion 2G will register with one burner opening although no other aperture portion will so register, thus assuring the use of a single burner.

Secured to the U-shaped supporting clamps 23 and similarly half encircling the pipe 1st on the opposite side are the substantially double l -shaped support 33, the eX- tremities of which are paralleled in the same 'horizontal plane in order to rest upon the may be so manipulated as to establish communication between the valve apertures 25 and the burner openings 25TL permitting the oil, still in its liquid state to escape exteriorly of the burner pipe and to drip there from upon the asbestos or other wicking in the tray 34 supported immediately below such burner pipe, until the said wick is saturated. An ignition of this wick when so saturated with the liquid oil will result in the action of 'the flames of such ignition upon the pipe 15, the deflector 21 serving to direct flames to this pipe 15 which llames otherwise would not reach the same, and accordingly serves to shorten the time required to bring sufficient heat to the coils 15-1G, through which the liquid oil is flowing on its way to its point of consumption in the burner pipe. Moreover the detlector 21 transmits the heat of this primary ignition directly to the vaporizing chamber of the pipe 11 in which the oil is first l cated to its point of vaporization before being led into the coils 15-16 where it is maintained at a. high temperature or is heated if so found desirable. The vapor upon leaving the burner pipe 211- escapes through the openings 25n in a manner directed by manipulation of the inner cylindrical valve and of course is ignited by the flame of the primary ignition in the tray 34, which latter being no longer fed by additional amounts of the liquid fuel from the burner gradually dies down after its purpose has been accomplished the heat from the vapor flames acting in a precisely similar manner upon the dellector 2l to maintain both the pipes 11 and 15 at their proper temperature. if all four (el) burners are to be lighted, portions of each of the elongated apertures are alined longitudinally of the cylindrical valve so as to successively register with the small burner openings 25, the indicator 3l occupying the position illustrated in TFig. 2.

Turning the handle 30 to either the right or I the left until the indicator 3l contacts with either of the points marked 2 on the handle scale of Fig. 2 will throw out either the end apertures or the central apertures as may be desired, depending upon whether a mild diffuse heat or a similarly mild but comparatively conccntrated heat is wished by the operator. If but a single burner is to be placed for operation, the valve is turned so that none of the apertures 25 register with L" their respective burner openings, save the especially elongated portion 26. ln every case control of the valve is facilitated by the tapered formation thereof which enables the operator to first loosen the valve in its seat by drawing outwardly upon the handle previous to rotating the valve to the desired position, thus obviating the ordinary wear and tear upon the valve member due to thc frictional contact with its seat and in no wise interfering with the proper positioning of the valve in any of the manners above set forth.

lt will be understood that the pipes 11, 15, 18 and 1l, may be connected with a stationary portion oi' the stove frame by a conventional form of bracket, not shown, or any other` suitable means. y

From the foregoing it will be clearly ap;D parent that means have been accomplished whereby the objects previously presented are capable of being attained so that this invention may lierefore be claimed as possessing the advantages and desirability set forth in such objects.
